Abstract: A viewing system operative to provide non-interfering color displays to two or more viewers disposed within a catadioptric projection display system. The non-interfering viewing system includes a projector subsystem 10 for generating a first image with radiant energy from a first set of color wavelengths and for generating a second image with radiant energy from a second set of color wavelengths. The first and second sets of wavelengths are spectrally multiplexed so as to include first and second red, blue and green wavelengths, respectively. A visor 32 is worn by a first viewer and includes a first triple notch filter. The first triple notch filter is adapted to transmit radiant energy of wavelengths included within the first set to the first viewer and to reject incident radiant energy of wavelengths included within the second set. A second visor 32 is worn by a second viewer and includes a second triple notch filter.
